[suggestion] Quick search improvements.

[gendalv]

1. Jump to and highlight the found item - even when it's found in an already selected session (current behavior: it's not highlighting anything if it's found in an already selected session, and no jumping).
2. Pressing 'enter' again should jump to the next found entry.
3. Built-in duplicates finder, auto-highlighting link duplicates.
4. Search through URL tick box (not just titles).
5. Rearranging links by dragging (so they open in different tab positions, when the saved window is loaded).
